71 mach 1 auto Cleveland car

[Harndog]

I have a chance to purchase this car but the motor and tranny is gone. It has new floor pans and a little exterior rust but not to bad. Whats the value of these big cars with the Cleveland motor? I think it's priced right but was curious what you guys thought. If not really that valuable I would most likely drop in a 408 and a built c4
